Fear of rhinos
My son has developed a new fear, I think.
Mom, are you absolutely sure there are no wild rhinoceroses around here?
I answer that I'm quite sure, but he remains unconvinced.
I'm not so sure. How can you be so sure?
My appeals to logic, reason and the globe are not working. My ten year old's assertion that if she were to run into a rhino, she'd prefer to run into a white rhino seems to have amplified the situation. They are bigger and stronger and she reasons her death would be much quicker that way.

I don't think she is helping any.
